Abstract

Dans un procédé de communication selon un mode de réalisation de la présente invention, un mot de code, qui est généré sur la base de codes de contrôle de parité quasi-cyclique comprenant des codes de contrôle de parité à faible densité quasi-cyclique de répétition-accumulation, est soumis à une permutation de bloc cyclique, l'ordre des blocs cycliques dans ce mot de code étant remanié, et chaque bit du mot de code qui a subi la permutation de bloc cyclique est mappé à un point de constellation d'une constellation non uniforme, ce qui permet d'améliorer la performance de réception.
